MACHINE FOR CUTTING GROOVES IN CARD-BOARD.

SPECIFICATION forming part of Letters l atent No, 442,878, datedDecember 16, 1890.

Application filed January 26, 1887. Renewed June 5,1889. Serial No313,113. (No model.) Patented in England January 8, 1387, N01321- Z'oall whom it may concern:

Be it known that I, J ACOB GEIGER, man ufacturer of card-board boxes,residing in Stutt gart, lViirtemberg, Germany, have invented certain newand useful Improvements in Outting Grooves in Card-Board, of which thefollowing is a specification. V

This invention was patented in Great Britain January 8, 1887, No. 321.

[O The object of my invention is to provide a new and improved machinefor grooving cardboard forthe man ufacture of cardboard boxes.

The invention consists in the construction and combination of parts anddetails, as will I5 be fully described hereinafter, and finally bepointed out in the claims.

In the accompanying drawings, Figure l is a front view of my improvedmachine for cutting grooves in card-board. Fig. 2 is an end View of thesame. Fig. 3 is an enlarged detail side view of the groove-cutters andgouge. Fig. i: is a crosssectional view of the same. Fig. 5 is ahorizontal sectional view of the same. Fig. 6 is a top view of a groovedcardboard blank with a longitudinal section of a card-board blank.

Similar letters of reference indicate corresponding parts.

The cross-piece q is held in the upper ends 0 of the two standards a a,and is provided with a longitudinal dovetailed groove to in each side,in which grooves the slides A are mounted to slide longitudinally, andon each slide A a vertically-adjustable holder 8 is held, which 5 has aslot, into which the slide A projects, said slide being provided with ascrew-shank 1 on which a suitable winged nut is screwed for locking theslide in place.

To permit of adjusting the holders verti' o cally,a screw 1 is passedvertically through each and is screwed through an aperture in thecorresponding slide A. The lower end of each holders is provided with afork t, on the shanks of which two rollers it, having cut tingedges, aremounted. A gouge r is held on the lower end of each holder 8, and itspoint projects in between the cutting-edges of the two rollers a, saidgouge serving to dig out that part of the card-board between the twoouts made by the blades of the rollers a. A curved piece \V, fastened tothe holder 8, rests upon the base of the groove between the cuttingedgesof the rollers and forces out from between the rollers that part of thecard-board cut out by said rollers. As shown in Fig. 3, another curvedpiece 00 is provided adjacent to the point of the gouge 'r, and servesto laterally guide the piece of pasteboard as dug out by the gouge, asshown in Figs. 3 and 5.

The slides carrying the holders on which the cutters are held can beadjusted a greater or less distance from each other, according to thedesired distance between the grooves, and the holders can be adjustedhigher or lower, according to the desired depth of the groove and thethickness of the card-board.

n represents a table or support resting upon brackets 0, which arevertically adjustable and can be locked in place by screws 1*.

m are gages on the table.

Having thus described my invention, I claim as new and desire to secureby Letters Patent-- In a machine for grooving card-board, thecombination, with a frame, of the holder 3, the cutting rollers or disksto, journaled in the forked lower end of said holder, the gouge r,

secured to an arm at the lower end of the holder, and the clearing-piece10, secured on the holder and having its end resting on the bottom ofthe groove formed between the two cutting-disks, substantially as shownand described.

2. In a machine for grooving card-board, the combination, with a frame,of the holders, the cutting rollers or disks u the clearing-piece to,having its free end in the groove between the cutting-edges of thedisks, the guide 00 on an extension of the holders, and the gouge r,substantially as shown and described.

In testimony that I claim the foregoing as myinvention I have signed myname in presence of two subscribing witnesses.
